IMPROVED METHOD 0F USING EXHAUST-STEAM FOR HEATING PURPOSES.

Specification forming part of Letters Patent No. 38,021, dated March 31, 1863.

To a/ZZ whom it may concern,.-

Beit known that I, BENJAMIN T. BAEEITT, ot' the city, county, and State of New York, have invented a new and useful Improvement in the use of exhaust-steam from engines and other apparatus as an agent for heating, boiling, or evaporating; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specication, said drawing representing a vertical sectional View of a steam-boiler, in connection with which my invention is applied.

This invention relates to reheating the eX- haust-steam from an engine or other apparatus, to use it for heating, boiling, and evaporating purposes, by means of the waste heat from a boiler or other furnace, thereby enabling it to be used successfully in many manufacturing processes for which, in the ordinary mode of using it Without reheating, its temperature is too low, and obtaining greater economy of fuel in other heating, boiling, and evaporating operations.

It consists in conducting the exhaustpipe into and for a certain distance through the chimney or tlue of the boiler or other furnace, and thence out to the vessel or apparatus to be heated.

To enable others skilled in the construction of steam apparatus to apply my invention to use, I will proceed to describe it, with reference to the drawing.

A represents a boiler for supplying steam to an engine. B is the furnace, and C is the chimney-flue. D is the exhaust-pipe of the steamengine, entering the chimney-flue at a convenient point and passing some distance through its interior, and leaving it at such point above, or beyond which it would not be profitable to continue it, and whence it passes to the apparatus in which it is to be used, in coils or other suitable arrangements of pipes or radiators.

Instead of the exhaust -pipe being run through the chimney flue, it may be run through any other of the ues or passages through which the heated gaseous products of combustion pass on their way from the furnace to the chimney, and, instead of its being heated by the waste heat from the furnace of the boiler in which the steam was generated, it may be heated by the waste heat from any other furnace, the position or arrangement of which is convenient for the purpose.

What I cla-im as my-invention, and desire to secure by Letters Patent, is-

Oonductin g the exhaust-pipe D into and for a certain distance through the chimney O or other iiue, and thence out to the vessel or apparatus to be heated, substantially as herein described.
